Gender Differences in Competition Emerge Early in Life

We study gender differences in the willingness to compete in a large-scale experiment with 1,035 children and teenagers, aged three to eighteen years. Using an easy math task for children older than eight years and a running task for the younger ones we find that boys are much more likely to enter a tournament than girls across the whole age spectrum considered here. This gender gap is observed already with three-year olds, indicating that gender differences in competitiveness emerge very early in life. The gap is robust to controlling for gender differences in risk attitudes and overconfidence.competition, gender gap, experiment, children, teenagers

The Development of Egalitarianism, Altruism, Spite and Parochialism in Childhood and Adolescence

We study how the distribution of other-regarding preferences develops with age. Based on a set of allocation choices, we can classify each of 717 subjects, aged 8 to 17 years, as either egalitarian, altruistic, or spiteful. Varying the allocation recipient as either an in-group or an out-group member, we can also study how parochialism develops with age. We find a strong decrease in spitefulness with increasing age. Egalitarianism becomes less frequent, and altruism much more prominent, with age. Women are more frequently classified as egalitarian than men, and less often as altruistic. Parochialism first becomes significant in the teenage years.other-regarding preferences, egalitarianism, altruism, spite, parochialism, experiments with children and adolescents

Strategic Sophistication of Adolescents: Evidence from Experimental Normal-Form Games

We examine the strategic sophistication of adolescents, aged 10 to 17 years, in experimental normal-form games. Besides making choices, subjects have to state their first- and second-order beliefs. We find that choices are more often a best reply to beliefs if any player has a dominant strategy and equilibrium payoffs are not too unequal. Using a mixture model we can estimate for each subject the probability to be any of eight different strategic and non-strategic types. The econometric estimation reveals that older subjects are more likely to eliminate dominated strategies, and that subjects with good math grades are more strategic.strategic thinking, beliefs, experiment, age, adolescents

Impatience and Uncertainty: Experimental Decisions Predict Adolecents' Field Behavior

We study risk attitudes, ambiguity attitudes, and time preferences of 661 children and adolescents, aged ten to eighteen years, in an incentivized experiment. We relate experimental choices to field behavior. Experimental measures of impatience are found to be significant predictors of health related field behavior and saving decisions. In particular, more impatient children and adolescents are more likely to spend money on alcohol and cigarettes, have a higher body mass index (BMI) and are less likely to save money. Experimental measures for risk and ambiguity attitudes are only weak predictors of field behavior

Impatience and Uncertainty: Experimental Decisions Predict Adolescents' Field Behavior

We study risk attitudes, ambiguity attitudes, and time preferences of 661 children and adolescents, aged ten to eighteen years, in an incentivized experiment and relate experimental choices to field behavior. Experimental measures of impatience are found to be significant predictors of health-related field behavior, saving decisions and conduct at school. In particular, more impatient children and adolescents are more likely to spend money on alcohol and cigarettes, have a higher body mass index, are less likely to save money and show worse conduct at school. Experimental measures for risk and ambiguity attitudes are only weak predictors of field behavior.experiments with children and adolescents, risk, ambiguity, time preferences, health status, savings, conduct at school, external validity

How strategic are children and adolescents? Experimental evidence from normal-form games

We examine the strategic sophistication of 196 children and adolescents, aged 10 to 17 years, in experimental normal-form games. Besides choices, we also elicit first- and second-order beliefs. The share of subjects playing Nash or expecting opponents to play Nash is fairly stable across all age groups. The likelihood of playing best response to own beliefs increases in math skills. Using a mixture model, about 40% of subjects are classified as a strategic type, while the others are non-strategic. The distribution of types is somewhat changing with age. The estimated error rates also show some dependency on age and gender

Social Preferences in Childhood and Adolescence: A Large-Scale Experiment

Social preferences have been shown to be an important determinant of economic decision making for many adults. We present a large-scale experiment with 883 children and adolescents, aged eight to seventeen years. Participants make decisions in eight simple, one-shot allocation tasks, allowing us to study the distribution of social preference types across age and across gender. Our results show that when children and teenagers grow older, inequality aversion becomes a gradually less prominent motivating force of allocation decisions. At the same time, efficiency concerns increase in importance for boys, and maximin-preferences turn more important in shaping decisions of girls.children, social preferences, age, gender, experiment

The development of egalitarianism, altruism, spite and parochialism

Abstract: We study how the distribution of other-regarding preferences develops with age. Based on a set of allocation choices, we classify each of 717 subjects, aged 8 to 17 years, as either egalitarian, altruistic, or spiteful. We find a strong decrease in spitefulness with increasing age. Egalitarianism becomes less frequent, and altruism much more prominent, with age. Females are more frequently classified as egalitarian than males, and less often as altruistic. By varying the allocation recipient as either an in-group or an out-group member, we also study how parochialism develops with age. Parochialism emerges significantly in the teenage years
